I feel like you are really picking apart hairs here.

There is not a huge difference between "the victim was not found to have been murdered." and "the jury did not find the evidence persuasive enough to decide guilt for the charged person for the charged crime". If you want to get really nitpicky, just because "the victim was not found to have been murdered", doesn't mean that they weren't murdered. Whether they were found to be murdered is a different statement than if they were actually murdered.
